High-Performance Industrial Copper Tubes – Class 0 & Class 1 for Air Conditioning and Refrigeration High-Pressure Copper Tubes for R410A and R32 Systems

The Industrial Copper Tube Class 0 is designed for high-performance air-conditioning and refrigeration systems, including industrial HVAC installations in commercial buildings and skyscrapers. It is compatible with R410A and R32 refrigerants, offering high pressure resistance, excellent thermal conductivity, and long-lasting durability.

• ASTM B280 Standard Copper Tubes — Class 0 Specifications

The Industrial Copper Tube Class 0 is manufactured in compliance with ASTM B280 (USA), the leading standard for air-conditioning and refrigeration applications. Minimum wall thickness:

1. 0.81 mm for tube outer diameters of 6.35 mm, 9.52 mm, 12.70 mm
2. 1.00 mm for tube outer diameters of 15.88 mm and 19.05 mm

These specifications ensure safe operation at high working pressures, making them ideal for modern HVAC systems that require reliability and strength. Premium Packaging – TOAN PHAT Branding Each copper coil is individually packed in a moisture-resistant bag with grain moisture inside to protect against corrosion. The tube is clearly printed with the manufacturer’s name TOAN PHAT, tube size, and ASTM B280 standard. Example:

• TOAN PHAT 9.52 mm × 0.81 mm × 15 m ASTM B280

After labeling, the packaging is shrink wrapped to ensure the product maintains maximum quality during storage and shipping. Class 1 Copper Tubes – Trusted International Standards The Industrial Copper Tube Class 1 is widely used in domestic and international HVAC markets, known for clean inner surfaces, precision manufacturing, and global compliance. Standards:

• ASTM B68 (USA) – Seamless copper tube standard for refrigeration and air-conditioning.
• JIS H3300 (Japan) – High-quality copper tubing standard used across Asia.

These certifications guarantee accuracy, cleanliness, and performance, making Class 1 copper tubes ideal for professional air-conditioning and refrigeration systems worldwide.
